Don't be scared Patric, spend every spare moment researching,,,,
I've done without technology for 3 builds, gained a few records, lost a few more, up until this build . Iv'e been lucky, relying on the 'ol jetting + 2.2 + a tad,, then this happened
So I went the 02 gauge route,,which tells me where I went wrong, and a heap of other stuff I'm yet to find the reason for, it also saved another piston hole by telling me this,,,,,
But it's up to me to find the reason why, but BEFORE the shyte hits the fan, not after.
